Second Call for Participation Shared Task CLPsych 2026: The 11th Workshop on Computational Linguistics and Clinical Psychology @ ACL 2026 in San Diego, USA (July 2-7 2026)

[iqra ali]

Dear all,

We are very excited to announce the second call for the 2026 CLPsych Shared Task 🥳 

This year's task will be held in conjunction with ACL 2026 in San Diego, USA (July 2-7 2026).

The 2026 task further advances work from previous years tasks by integrating dynamic mental health modeling, emphasizing the identification of key self-state elements leading up to mental state changes over time. Participants will analyze temporally ordered sequences of social media posts to characterize detailed psychological processes, key changes, as well as the interplay of such self-state processes leading up to the changes. Grounded in the MIND framework that conceptualizes self-states as combinations of Affect, Behavior, Cognition, and Desire (ABCD) components, it aims to further explore the fine-grained elements contributing to changes. The core objective of the shared task is to develop computational models that can identify adaptive and maladaptive self-state dimensions as well as changes over time across social media timelines aiming to characterize and summarize self-state sequences leading to such changes.

Task description
Participants will develop systems that emulate a structured human annotation process to model mental health dynamics over time:

• Predict adaptive and maladaptive ABCD element combinations for each individual post. 
• Identify moments of change in mental health social media trajectories using longitudinal signals.
• Generate concise, interpretable self-state summaries leveraging the identified ABCD elements and contextual information leading up to changes in the user timeline.

For registration please complete:

• One team registration form
• One individual registration form per team member.

Registration Deadline: February 15th 2026 (AOE)
